The Plesk backup/restore utilities allow backing up the Plesk server configuration information as well as its current content (client accounts, domains and so forth) as they are at a certain moment in time - the moment when the backup is carried out. They also allow restoring these data at the server. This proves useful when either you need to execute a system operation, which can influence such data (for instance, upgrade the OS that Plesk is running on), or simply for the safety purposes. The two utilities that provide these functions are: Plesk Backup and Plesk Restore.
